Over the 21 days we will introduce you to the eggs parents! We will also tell you about what is happening in the egg at key points.

Start – Day 0 if you like!

17 eggs were put into the incubator. Each egg was given a number and weighed – why not start recording the weights with us.

Which egg is heaviest?
You could plot a graph to see which egg is the heaviest.
Do you think this will give the biggest chick?

Day 1

All the important parts of chick start to develop

Or first 24 hours after putting in incubator sees the start of growth for everything of huge importance to the embryo : the head, ears, eyes, spinal column, nervous system (including the brain) and heart. You cannot really see this but the embryo basically develops and ‘blob’ in the yolk – seen in picture superimposed on an egg.

As early as 72 hours after the start of the process, tail, wing and leg buds appear and the heart begins to beat.
